While I'm impressed by the graphics I think the question was why does it make a difference wearing shoes with nothing supporting the arch in your foot when compared to lifting in bare feet i.e. both surfaces are flat beneath your feet so why does it matter that one is the floor and the other is your own portable "floor"?
the inside of the shoe compresses, the floor usually doesn't.
so if the shoe is moulded to your arch, it will compress evenly, if it isn't, it compresses oddly compared to the arch.
